A New Map of the Universe to Deep-Sea Bacteria that Could Help Us Find Aliens
Holiday Weekend Edition
This weekend’s stories include: Enormous Gravity ‘Hum’ Moves Through the Universe and The Very First Processes That Could Have Formed Life On Earth.
A New Map of the Universe, Painted With Cosmic Neutrinos that shows a diffuse haze of cosmic neutrinos emanating from throughout the Milky Way, but strangely, no individual sources stand out. “It’s a mystery,” said Francis Halzen, Vilas Research Professor and Gregory Breit Professor at the University Wisconsin-Madison--a theoretician studying problems at the interface of particle physics, astrophysics, and cosmology. "Since 1987, he has been working on the IceCube project, beginning with the AMANDA experiment, which led to the construction of IceCube, a kilometer-scale neutrino observatory at the South Pole."
Quanta: An Enormous Gravity ‘Hum’ Moves Through the Universe: Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos. The cause? Probably supermassive black hole collisions, but more exotic options can’t be ruled out. "The finding has opened a wholly new window on the universe, one that promises to reveal previously hidden phenomena such as the cosmic whirling of black holes that have the mass of billions of suns, or possibly even more exotic (and still hypothetical) celestial specters."
These Deep-Sea Magnetic Bacteria Could Help Us Find Aliens--"Scientists have found an entirely new class of magnetically sensitive bacteria that live nearly two miles beneath the surface of the Pacific Ocean, a discovery that could shed light on the emergence of life on Earth, and the potential existence of aliens on other worlds, reports a new study," reports Becky Ferreira for Vice Science.
A Glimpse Into The Very First Processes That Could Have Formed Life On Earth, reports NASA Astrobiology. "A new technology has shed further light on the age-old question: what are the origins of life on Earth?"
The Cosmos Is Thrumming With Gravitational Waves, Astronomers Find--Radio telescopes around the world picked up a telltale hum reverberating across the cosmos, most likely from supermassive black holes merging in the early universe, reports Katrina Miller, a science reporter, recently earned a Ph.D. in particle physics from the University of Chicago, for The New York Times.
New York Times Audio: What to make of the latest allegations of a government cover-up of Aliens.
A 'captured' alien planet may be hiding at the edge of our solar system - and it's not 'Planet X'—The cold and mysterious Oort cloud at the edge of our solar system may be hiding a rogue exoplanet, new research suggests, reports Live Science.
Stunning JSWT image sees Saturn show off its glowing rings: A strange and unfamiliar view of Saturn has been captured by the James Webb Space Telescope to help researchers identify its smaller objects and structures, reports New Scientist.
Why do we all live on Earth?--There's an entire Universe out there. So, with all that space, all those planets, and all those chances at life, why do we all live here? probes Ethan Siegel for Big Think.
Scientists Discover Ancient 'Lost World' That Rewrites History of Life on Earth--The remains of a "lost world" of ancient organisms that are likely ancestors to all plants and animals, including humans, have finally been detected, reports Becky Ferreira for Vice Science.
A Supermassive Test for Einstein’s Famous Theory--How a gravitational wave background re-opens the book on general relativity, reports Nautil.us. "Pulsar pulses are so exact and predictable that they are nature’s original gravitational wave detector.
Massive ‘Gravity Anomaly’ Caused by Ancient Sea Remnants Deep Inside Earth, Study Says--The remains of the prehistoric Tethys Ocean are now inside the Earth, causing a massive gravity anomaly in the Indian Ocean, reports Vice Science.
